Johns Creek homes develop HVAC mold when condensation collects in the coil cabinet or drain pan or forms on ducts running through attics and crawl spaces. Solving it means fixing the moisture, then cleaning or replacing the affected parts. Call the number on this page to be connected with a local mold remediation company in Johns Creek.
Johns Creek in brief
Johns Creek incorporated in 2006 from crossroads communities such as Newtown, Ocee and Warsaw, about 22 miles northeast of downtown Atlanta. The Chattahoochee River runs along roughly 13.5 miles of its southern edge. Homes with more than one system often have equipment in the attic, where heat and humidity make condensation and drain problems more likely.
What to do now
- Turn the system off if you can manage without it. EPA advises not running a system you know or suspect is contaminated.
- Check the drain pan under the indoor unit and the outdoor end of the condensate line. Standing water or a dry outlet in summer points to a clog.
- Photograph any growth on grilles, the air handler cabinet or duct surfaces you can reach safely.
- Note which zones smell musty. In a multi-zone house this helps narrow the search to one unit.
- Keep indoor humidity under 60 percent with a portable dehumidifier if the AC is off.
- Do not spray products into the ducts. Treatments can mask the smell while the source stays wet.
What you see and what usually causes it
| What you see | Likely cause |
|---|---|
| Water dripping from a ceiling under the attic unit | Blocked drain line or overflowing secondary pan |
| Growth around one supply register | Cold air meeting humid room air, or a leaky boot pulling in attic air |
| Musty smell in one zone only | Wet coil or pan on that zone's unit |
| Dark patches on attic duct wrap | Ducts sweating where insulation is thin or torn |
| Damp rooms despite steady cooling | Oversized unit that short-cycles and removes little moisture |
Cost factors
Angi's Atlanta cost guide reports HVAC system mold remediation at $3,522 to $11,740. In a large home the number of systems and total duct length drive the price, followed by duct type, since EPA says moldy fiberglass duct board or lined duct cannot be effectively cleaned and should be replaced. Attic access, containment and any rebuild work also count. Johns Creek requires a building permit for interior alterations that involve drywall or framing, so if ceilings are opened to replace ducts, ask whether the patch-up needs one; the city's help line is 678-512-3250.
